SAPGUI WSAEWOULDBLOCK: Resource temporarily unavailable

SAP on single Windows Server.

For Me through VPN:

  1. I can ping both the IP address and domain.
  2. I can connect to SAPGUI.
  3. When I telnet to IP Port 3200, get a black screen.
  4. "netstat -a" is slow, but executes, but "netstat -an" is instantaneous.

My developer through VPN:

  1. Can ping both IP and domain, but can't connect through SAPGUI from two different machines.
  2. Have tested with all firewalls (server and client) off - doesn't work.

Hosts file on server correctly has entry for domain. Services file has entry for sapdp00:3200 .

Reviewed both 124562 Hostname resolution problems (DNS timeouts) and 23538 Problems due to inconsistent host name notation but don't know that I've got a good answer.

I'm not a network guy (or really Basis). Hoping someone can give me some pointers of what to look for.

Thanks in advance.

    Tammy,

    Thanks for the input. I have verified that both private and public network firewall is off.
